AI programs. Defined scope, known price, clear outcome.
BigStep works in structured programs, not open-ended retainers. Each one comes with a defined scope, a price range, and a clear outcome. You pick the right fit, we scope it for your situation in one call, and work starts.
Start free with a 90-minute working session. Or go straight to the program you need.
How pricing works
Every program shows a price range. That range reflects what we know before we have spoken with you. After one call, we give you a single number for your specific situation. That number is what goes on the invoice.
What moves the price within a range varies by program. The main factors are how many systems are in scope, how much existing data or infrastructure there is to work with, and how complex the setup is. Each program page explains the specific variables.
Find your starting point
Not everyone starts from the same place. Some need to understand their situation before building anything. Others are ready to build right now. Use the groupings below to find where to start. If you are not sure, book a free Possibilities Session. It is 90 minutes and costs nothing.
Diagnose
Before you build anything, you need to understand where the opportunity is, what the gaps are, or what is already broken. Diagnose programs run for one to three weeks and end with a report, a score, or a roadmap. No code is written.
Right for you if you want clarity before you commit to building anything.
Build
Short, fixed-scope sprints to get working AI in your hands. Not a plan to build something. The thing itself. At the end of a Build sprint, you have something you can use.
Right for you if you know what you want and want it done in a few weeks.
Launch
For teams that have built something and are ready to take it to production. Launch programs handle the infrastructure, the evaluation, the scaling, and the handover. This is where prototypes become products.
Right for you if you have something working and need to take it to production.
Transform
Programs that change how your engineering team works. Not what they ship this quarter. How they build things going forward.
Right for you if you want your team to build differently, not just ship one more thing.
Embed
BigStep engineers work inside your team, on your codebase, at your pace. Available as a full-stack pod, a standard pod, a single embedded engineer, or a structured eight-week sprint.
Right for you if you want BigStep engineers working inside your team on an ongoing basis.
Run
Once your platform is live, we keep it running. Monitoring, incident response, and a monthly health report. This is not a development retainer. It is operations and nothing else.
Right for you if your platform is live and you need someone keeping an eye on it.
What sets us apart
You know the price before work starts.
Every program is scoped and priced after one call. The number does not change mid-engagement. We absorb overruns, not you.
Our engineers have shipped AI in production.
Not demos. Not proofs of concept. Working systems handling real traffic and real failures at companies across the US, UK, and Europe.
Senior engineers only.
There are no junior developers on our projects billed at senior rates. The person scoping the work is the person doing it.
We say no when it is not the right fit.
If a program cannot succeed in your situation, we say so on the first call.
You pay for the outcome, not the hours.
Every program has defined deliverables. The price is for those deliverables, not for the time it takes us to produce them.

Prices are confirmed after a discovery call.
Common questions
Yes. The price range narrows to a single number after your discovery call, and that is the number on the invoice. We do not adjust mid-engagement.
No. Most clients do, because it tells both of us what the right next step is. But if you already know what you need, you can go straight to any program.
Get in touch. Most situations map to an existing program. If yours does not, we will say so on the first call rather than forcing a fit.
A 90-minute working session with a BigStep engineer. We map your workflows, identify where AI can help, and send you a two-page written summary. No pitch. No prep required from you.
For Embed programs, yes. You set the brief and our engineers work inside your team. For everything else, we work on fixed-scope programs only.
Yes. Our programs are designed primarily for US and UK enterprise clients, but we work globally.
Start with something free
The Possibilities Session is a 90-minute working session with a BigStep engineer. You tell us what you are building or what problem you are trying to solve. We come back with a two-page summary of where AI can help and where it cannot. No cost. No obligation.
Already know what you need?
If you know the program you want, or if your situation is specific enough that a session would just slow you down, get in touch directly.
